PATENT CAN ENDI NGTOR HEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 605,189, dated June 7, 1898.

Application filed October 27, 1897. Serial No. 656,541. (No model.)

To all whom it may concern:

Be it known that I, HENRY ScnAAKE, a citizen of the United States, residing at New \Vestminster, in the Province of British 00- lumbia, Dominion of Canada,have invented certain new and useful'Improvements in Can Ending or Heading Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to a certain new and useful can ending or headingmachine for use in canneries or packing establishments; and it consists in the arrangement of parts and details of construction, as will be hereinafter fully set forth in the drawings and described and pointed out in the specification.

The invention is designed more especiallyfor use in the ending or heading of what are known as filled cans or those which have been packed with fish or other articles; and the object thereof is to provide a simple, effective, and inexpensive machine for the successful heading or ending of the filled can.

In order to comprehend the invention, reference must be had to the accompanying sheets of drawings, wherein Figure 1 is a side view in elevation of the machine. Fig. 2 is a front View in elevation of the machine, the discharge-chute or runway for the headed can and its supportingbracket being broken away. Fig. 8 is a broken detail view in side elevation. Fig. 4. is a bottom plan view. Fig. 5 is a top plan view of the mechanism illustrated by Fig. 1. Fig. 6 is a cross-sectional top plan View taken on the line so 00, Fig. 3. Fig. 7 is a detail bottom plan view of one of the can head or end hold ing devices; and Fig. 8'is avertical sectional the standard being inwardly curved and ter minating in a bearing a. Near the lower end of the standard is attached the bracket A which carries the bearing a. In the bearings a aworks the vertical shaft A, which shaftat its lower end carries the bevel-gear 2, which meshes with the pinion 3 of the hori zontal drive-shaft 4. This drive-shaft works in suitable bearings and has secured thereon the belt-wheel 5, being driven by means of a belt (not shown) working over the beltwheel 5.

To a bracket a inwardly projecting from the supporting-standard A, Fig. 2, is fastened the eccentric cam-ring B, and to a similar bracket a is bolted or otherwise secured the eccentric cam-ring B while between these cam-rings is located the cam-ring 13 which is bolted or otherwise secured to the projection a These cam-rin gs surround the driveshaft, as shown.

Upon the vertical shaft A is secured the square hub 0. Within each face of the hub in the present case are cut the vertical guidechannels I). In these guide-channels work the slide-plates C, said slide-plates being held in vertical position by means of the plates 79, secured to the edges of the hub C, Fig. 6. At the lower end of each slide-plate is secured upon the pin or stud b outwardly projecting therefrom, the roll 0 which rolls during the rotary movement of the hub 0 travel within the eccentric groove D of the cam-ring B in order to raise and lower the slide-plates. Between the arms d, projecting slightly out wardly from the upper end of each slide-plate O, is fulcrumed the ear cl of the can-holder D. From the lower end or bottom of each can-holder projects the arm D to thefree end of which is secured the roll D This roll travels or works within the eccentric groove D cut in the cam-ring B so as to move the can-holder D in and out during the rotary movement of thehub O. The arm D works between the guide-ears d outwardly projecting from each slide-plate C, Fig. 1.

Each can-holderis semicircular or cupshaped, the edge or side 6 extending beyond the edge or side 7, Fig. 6, and the edge 6 terminates in a rearwardly-extending "inclined flange 8, while the edge 7 terminates in a forwardly-inclined flange 9. The flange 8 and the flange!) approach within ashort distance of each other and serve as guards to prevent the cans entering between the can-holders while the said holders approach the feed-belt or conveyer E, which conveys the can E toward the heading or ending machine.

To the hub 0, immediately below the camring B Figs. 2 and 8, are secured the canhead-holdin g plates E These plates are cut away on their inner or under face, so as to form a can-head seat f. The plates E serve as the stationary portion of the canhead holders, and to each plate is movably secured by pin f the face-plate E Each face-plate at its free end is provided with an upwardlyprojecting arm f, to the outer end of which is secured the roll E The arm f works in a cut through the plates E (shown in dotted lines, Fig. 5,) and the roll E secured to the outer end thereof, rides or works within the eccentric groove h, cut in the under face of the cam-rin g B as the can-head holder is carried around by the rotation of the hub 0. As the roll E moves or travels within the eccentric groove h the movable face-plate E of the can-head holder is moved inwardly and outwardly. Each face-plate E is cut away centrally, and the outer face or edge of the cut-away portion is chamfered, as shown at h, Fig. 7, so as to permit the upper edge of the can-body to be gradually forced within the flange of the can-head retained within the seat f. The can head or end H as delivered from the feed-chute or runway H moves between the plate E and the movable face-plate E into the can-head seat f, being held inplace by the said movable face-plate, which when closed encircles at least one-half of the can-head flange. The can-head is thus held in place and prevented from moving from within its seat until the face-plate E is swung outward in order to give clearance to the canhead.

holder serves as a finger which engages the can and gradually removes the same from off the conveyer or feed-belt into the can-holder.

The endless conveyer or feed-belt traveling with greater rapidity than the can-holder, it

is apparent that ample time is given in which to remove the can and place the same within the holder. a slight distance below the level of the conveyer or feed-belt. Consequently the cans will be tilted into the holders. The moment the filled can has been placed within the holder the roll C of the slide-plate G is carried within the upwardly-inclined portion 12 of the cocentric groove of the cam-ring B and forces the slide-plate C upwardly or toward the cam-ring L in order to place the inner edge of the can-body projecting beyond the open end of the can-body holder within the inner portion of the flange of the can-head held within the can-head holder. As the canholder is carried by the upward movement of the slide-plate toward the can-head flange the roll D secured to the arm D projecting The bottom of the can-holder is from the bottom of the can-body holder, moves within the outwardly-inclined portion of the eccentric groove of the cam-ring B During the travel of the roll D within this portion of the eccentric groove the can-holder is gradually thrown from an inclined to a vertical position, so as to gradually force the entire circumference of the can within the flange of the retained can-head, being guided therein by the chamfered edge of the movable portion of the face-plate E of the can-head holder. After the end of the can has been headed or the end placed thereon the roll E connected to the face-plate E moves within the outwardly-inclined portion of the eccentric groove of the cam-ring B and swings the free end of the movable face-plate E outward, so as to release the headed can-body, which is forced from within the can-head holder by means of the plunger-rod 7c. The head of this plunger-rod rests within the socket 10 out in the plate E the rod working through the bracket 10 and an opening through the plate E Fig. 8. This plungerrod is held upward, so as to maintain the plunger-head in its seat, by the spring M, which spring surrounds the plunger-rod and is interposed between the bracketvk and the collar j, secured to the said rod. As the canhead holder is carried around the plungerrod moves therewith. During the rotation of the mechanism the free end of the plungerrod moves under the inclined cam-plate K, secured to the cam-ring B and is gradually forced downward, the plunger-head, bearing against the headed end of the can, gradually forcing the end of the can from within the Duringthe operation of heading, topping, or ending the filled cans the can-holders approach the conveyer or feed-belt with the upper end portion thereof outwardly inclined. As carried past the lower end of the conveyer or feed-belt E the projecting edge 6 of the:

can head holder. The can as discharged from the machine enters within the dischargerunway K The can-head chute or runway is set at an incline, so that the head moves down by gravity, and as the heading-machine is set at an angle or inclination no mechanism is required to place the can-heads in the can-head seats. To insure the said heads moving the full dis tance within the can-head seats prior to the cans being elevated, there is attached to the can-head chute or runway the curved arm L, which arm fits between the plates E and the movable face-plate E As the can-head is carried around this arm gradually forces the same the full distance within its seat. The lower end of the can-head feed-chute or runway is supported by the bracket L, which projects from the bearing a, Fig. 1.

The axle Z of the lower end roll L of the can-conveyer or feed-belt E works in bearing of the bracket L upwardly projecting from the standard A. This bracket also supports the guard-rail Z at the lower end of the can-conveyer or feed-chute, which prevents the cans falling ofi of the said conveyer or feedbelt while being fed into the can-hold ers. By means of the curved straps or bands 1 one of which projects from the lower end strap or band is secured to and projects from the bracket Z upwardly projecting from the cam-ring 13 Fig. 2, the cans are prevented from accidentally slipping or falling out of the can-holders.

As the plunger-rod 7c is moved downward to force the can-head from within its seat the roll 0 of the slide-plate rides upon the downwardly-inclined portion 13 of theeccentric groove of the cam-ring B, so as to lower the said slide-plate and place the can-holder carrying the headed can in line with the discharge chute or runway K In the bottom of each can-holder is cut a groove m, within which fits the angle-plate 'm, Figs. 1, 2, 3, and 6. This plate actsas an extracting device for removing the headed can from within the can-holders as they reach the discharge chute or runway. To the forward end of this angle-plate is attached the depending roll m This roll as the holders approach the discharge chute or runway rides upon the outer face of the inclined camplate 19 and gradually draws the angle-plate or extracting device outward. As thus moved the said angleplate or extracting device forces the headed can from within the canholder into the discharge chute or runway. The moment the roll m moves off the camplate the pressure of the compressed spring 19 forces the angle-plate or extracting device inward. This spring is attached to a stud p downwardly projecting from the can-holder, and a downward extension p of the angleplate or extracting device, Fig. 3.

By preference the upper end of the discharge-runway is supported by a curved bracket M, upwardly projecting from the bearing a. The headed cans as delivered to the discharge chute or runway are thrown from a vertical into a horizontal position by means of the deflecting-plate M, Fig. 1.

The axle Z of the roll L of the can-conveyer or feed-belt is driven from the drive-shaft 4: by means of the sprocket-chain 14:. This chain works over sprocket-wheel 15, secured upon the drive-shaft t, and over sprocket-wheel 16, mounted upon the short shaft 17,Figs. 1 and 2. The sprocket chains also engage with the sprocket-wheel 18, mounted upon the axle Z, and thus impart motion to said axle and roll L The drive mechanism is so regulated that the conveyer or feed-belt E travels somewhat faster than the rotation of the heading-machine. This is necessary in order to insure the cans being safely deposited in the canholders prior to the holders being carried past the can-,conveyer or belt.

Having thus described my invention, what I claim as new, and desire to secure protection in by Letters Patent, is-- 1. In a machine for heading or ending filled cans, the combination with the rotating shaft, of the hub fastened thereon, the vertical can holders, the can-head holders, of mechanism for placing the filled cans in the holders in a vertical position and of devices for moving the can-holders toward the can -hcad holders in order to place the inner edge of the can within the inner portion of the flange of the retained can-head and throwing the can-holders from an inclined position into a vertical position, so as to force the entire circumference of the can-body within the flange of the can-head.
